THERMAL MODELING
Empirical Confirmation of Via Temperatures
Current doesn’t determine the temperature of a via; rather, it is the temperature of the associated traces. If the traces are sized correctly for the current level, much smaller and fewer vias are required to transition between trace layers than has been previously believed. In practical terms, designers can have much greater flexibility in freeing routing channels underneath the traces on their boards.
